PLEASE HELP Two forces are applied to a 2.0-kilogram block on a frictionless,
horizontal surface, as shown in the diagram.
F = 2.0 N
F2= 8.0 N
2.0 kg
Frictionless Surface

Find the vertex(use the completing the square method), findthe x- and y-intercepts, and sketch the graph offunction. y = 2x2 + 4x - 1

Ineed the answers for these promblems i have

Two forces produce equal torques on a door about the door hinge. the first force is applied at the midpoint of the door; the second force is applied at the doorknob. both forces are applied perpendicular to the door. which force has a greater magnitude?
